The NAD is an integrated amp and the Nuforce is only a power amp. Going from an integrated to a separate pre/power opens up a whole new discussion.
The OP is currently using a Denon AVR receiver. I don't know if the Denon has pre-out capability to enable use of a separate power amp and if the OP has that intention? Or, to completely replace the Denon?
